and projectingfrom the opposite sidesnf. a

bolster 42. The bolster 42 is'provided' on its ends with studs 43 which are engaged with springs 44 secured to the lower side of the forward ends of the side .bars of the frame 1 as shown. By thus arranging the runners 35' it will be seen. that they maybe swung laterally to steer the sleighin the desired direction and that they:will, also be The forward end the sleigh is supported Ion 'steering runners. 35 comprising. upper runner bars 6,1, pivotally mounted on studs 43 when passing over obstruct-ions or uneven surfaces. The runners 35 are pro- --permitted to in a vei'tical plane on the wardly th rough the-bottom of the sleigh body within convenient reach of the opera;

vided with shoes or wear plates 45 and'are porting frame 36.

suitably braced as is also therunner supa In order to guide or. steer the sleigh in the des red direction, I' provide. a steering mechanism comprising runner engaging rods 46 having on,their inner ends eyes with which" are engaged bolts 47 whereby the inner endsof the rods "are securedto the inner sides of the-upper bars of the runners a short disrunners with the frame 36. 'The forward ends of the ro'ds'46 are bent inwardlyto a slight extent toward the center of the space Also connected with between the runners. the bolts 47 are bracing rods 48 which exvtend back along the inner sides of the upper I 'tance ahead of the pivotal connection of the 1 bars of the runners and are secured thereto as shown. The forward ends of the rods 46 are loosely connected by links 49 to the forwardly projecting right angular lower arm 50 of a crank shaft 51 which is, mounted in the lower bottom 52 of the forward endyof the sleigh body. Qn-thehpper' end of the shaft 51 is Jan upper forwardly projecting right angular crank, 'arm' 53 which is. disposedand operates between the lower bottom' 5270f the sleigh andan upperfalse hottom 54 arranged above the lower bottom be had to thespace between said bottoms, said-panel being removablyheld in place by.

'- Suitably .mounted at its lower end in'the I.

bottoms'52 and 54 of the sleigh body is a steering rod or shaft 57 having on its upper end a hand wheel 58 and on its lower end a crank. arm 59 which is disposed and works in the space 'between'the'bottoms 52 and 54 and isconnected at its outer-end by a link 60 with the forward end of the upper crank arm 53 of the crankshaft '51. .By thus constructing and arranging'the steering mecha- ,nism, it willbeseen that the runners 35 may be readily turned by the operator to guide or steer the machine in the desired direction. 'From-thefor egoing description taken in connection with the accompanying draw- I 'ings, the construction andwopera'tion of the invention will be' readily understood with.-

out requiring a more. extended explanation.

Various changes .in the form, proportionand. the minor details. of construction may be resorted to without departing from the"- principle or sacrificingany of the advantages of this invention 'asdefined an claimed-v. -Havi-ng thus particularly described my invention, what I claimis:

1 {In a "device of the character described.

U shape, the depending ends of which form bearing poets,

front runners. having upper and ioiver bars pivotally mounted on the upper and lower ends of said posts, a link connection between the front ends of the front runners whereby they may be turned in unison, and operating mechanism connected to the front runners to guide said sleigh.

'2. 1n :1 sleigh of the character described, a front runner supporting frame of inverted U shape, the depending ends of which form bearing vests, front runners having upper them, upper pii'ote passed vertieit'iand lower bars to receive said ost between rough lower the upper burr; and into said post.

' pii'ots' on the bottoms of said posts and mounted in sockets in the tower bars the front runners, :1 link conneeticu between the front ends of the front runners whereby they may be turned in'unison, and operating mechanism connected to the front runners for guiding said sleigh.

In testimony whereof I. have here nto set iny'hzind in presence of twosubsciibing witnesses.
